Subject: drm/bridge: tc358767: Do not cache dsi_lanes twice
Git-commit: 5bdaaf4fbf85d47d08f76f41108d8d3bbdf15f1c
Patch-mainline: v6.0-rc1
References: jsc#PED-1166 jsc#PED-1168 jsc#PED-1170 jsc#PED-1218 jsc#PED-1220 jsc#PED-1222 jsc#PED-1223 jsc#PED-1225 jsc#PED-2849
The DSI lane count can be accessed via the dsi device pointer,
make use of that. No functional change.
